To all 't0/tom t may concern:

Be it known that l, RAYMOND FnnorvAL PAYNE, a Subject of the King ofl Great Britain, residing at Leeds, in the county of Yorkshire, England, have invented certain new andl useful improvements in Rotary Printing-Machines, of which the following is a full, clear, and exact description.

llfhis invention relates `to rotary printing machines and has special application to machines in which more than one design is printed for each cycle of the machine. A machine of this character generally utilizes a plurality of rotary cylinders each of which is adapted to carry either a single or a plurality of design surfaces which come into printing contact with the printing surfaces on an associated cylinder. llt has heretofore been proposed to construct a machine of this character sovthat the design cylinders can have a rotary adjustment imparted to them during their rotation for thepurpose yof altering the register of the design surfaces with the surfaces with which they comeinto rlhe object of my invention is to improve generally upon the devices which have been produced for this purpose vand to provide a construction wherein the adjustment may be accomplished in a simple and expeditious manner.

lVith these and other objects in view, my invention consists of a form of driving gear for rotating the cylinder, which gearingv comprises means including a member movable longitudinally with respect to the axis of one of the cylinders for effecting the rotary adjustment, without disconnecting the driving gear.

ln the accompanying drawings, Figure l is a plan partially in section of the end portions of a design cylinder and an associated cylinder, together with a driving gear therefor, embodying the features of my invention; Fig. 2 is a detail view showing in elevation the main essentials of the driving gear shown in Fig. l; Fig. 3 is a plan similar to Fig. 1 Vshowing another modification of the driving gear;- and Fig. .4i is a detail view in elevation of a portion of the driving gear shown inFig; 3. I i

Referring generally to the construction shown in Figs. l and 3, 1 designates a cylinder adapted to carry either a single or a plurality of design surfaces, and 2 designates tion.

the cylinder associated therewith which is adapted to carry surfaces in printing contact with the, design surfaces.` rlfhe associated cylinder 2 may consist of an impression cylinder which is adapted to carry the sheets upon which the designis to be printed, or if the invention is to be utilized in connection with an offset printing machine the cylinder 2 would constitute the transfer cylinder which would have on its surface the blankets of rubber or the like adapted to receive the imprint ofthe designs, the invention being capable of utilization with any type of printing machine having two associated cylinders whose surfaces are in printing contact. lt may be here stated that while l have shown, for the sake of clearness, a single design cylinder, yet in the machine where the invention is particularly adaptable, there would be a plurality of such cylinders, arranged in printing contactwith the associated cylinder.

`Referring now to Fig.` l, wherein one form of the'improved driving gear for the cylinders l and 2 is shown, which is adapted to simultaneously rotate the cylinders continuously and to impart thereto an addtional rotary adjustment during their rota- 'lhe cylinders l and 2 are mounted `upon shafts 3 and i, respectively, only a portion of which are shown. A gear wheel 5 is mounted upon the shaft l and is rigidly vsecured to the cylinder 2 by means'of bolts 6. The gearwheel and connections for the design cylinder l comprise a hub 7 which is mounted upon the shaft 3 to slide longitudinally thereon, and is prevented from independent rotation of this shaft by a key S. Surrounding the hub 7 is an annular gear wheel 9 whose outer peripheral surface is provided with teeth adapted to mesh with the gear wheel 5 carried by the cylinder 2. rlhis annular ring or gear whe-el is connected or secured to the cylinder 1 by means of bolts l0 passing through elongated segmental-shaped slots 10 in the same, which connection permits relative angular movement between the gear wheel and cylinder, while preventing displacement of the gear wheel longitudinallyof the. axis of theA cylinder.

lf desired the gear wheel 5 carried by the cylinder 2 may be provided with an annular flange l1 and a portion of the outer peripheral surface of the annular ring or gear wheel 9 cut away to provide a recess forming a shoulder 12 against which this flange bears, and therefore prevents any longitudinal movement V0f the yannular gear Wheel. The annular gear wheel 9'is connected to the hub 7 by a single key or a Y 'plurality of keys 13 sunk into the inner pe- Vripheral surface ofthe ring to hold them 'in-place, which keys are adapted to fit into .Y faces of both cylinders. It is apparent that the key V'8V might be set at an angle to the axialplanes instead of keysrl, which con,-` `struction would give the same result.

' YAn annular groove or `hub slot 14 is providedV inl an extension of the hub 7 into which is fitted aV sliding collar 15. [This collar is connected to a yoke lever 1G pivoted yas at ,17 to Va stationary part of the machine. The other end of the lever 16 carries a thumb adjusting screw 18 which is mounted intrunnionv bearings andY has its end Ythreaded into a stationary part 19 carried bythe frameiof the machine, not shown. To adjust the hub 7 longitudinally of the shaft 3, therefore, it is only necessary to turn therthumb screw 18 until the lever 16 f has beenV moved the desired amount to ob- 'tain the adjustment, in which 'position they hub 7`will be held until itis again displaced by a furtherV manual adjustment of the parts, the adjusted position being that in kwhich the cylinders are in the desired register. f

Y In Fig. 3, there is shown another modificationV forYV eecting the rotary adjustment- Ywhich consists injloosely mounting a gear V`.rwheell23'on the shaft of thecylinder 1 and u connecting this `gear wheel to the cylinder by meansv of slide-ways orV guides 24 projecting from the end face of the cylinder, which slide-ways have their bearing surfaces inclined to the-axial planes of the cylinder, passingthrough the same. V4The ends of these slide ways Vprojectthrough segf VV'mental shaped''openings in the web ofthe l 55 gearwh'eel 23 andv oni the' rib-'formed between the openings, a block 25 Vis pivotally mounted-which block has its side faces cut Yatan angle to ride in the slide-ways 24.

j While one suchconnection is shown,- itY isY y i 6.0

evident that if desired, a plurality of such blocks andslide-ways may be utilized in Y "order, to 'provide' a more YsecureV connection Vbetween the; geanwheel and the cylinder.

- Y .il `When the gear-'wheeljis moved'longitudi- 1 "'tr'nallyv'on itsshaft,the angular position of nal movement of said the gear wheel with respect to the design cylinder will be changed and will thereby effect the rotary adjustment of the cylinders as has been described.

It will be apparent from the modifications herein set forth that the necessary rotary adjustment may be obtained in various ways without disconnecting the driving gear and it is not my intention to limit myself to any particular form, but only by the scope of the claims appended hereto.

I claim 1. In a rotary printing machine, two cylinders operatively associated with each other, and adapted to carry printing surfaces, gearing connecting said cylinders, comprising a gear wheel mounted Vfor rotation with one of said cylinders and a gear wheel and connections from said last named gear wheel to the other of said cylinders, said last named gear wheel and connections -havinga part mounted for rotation with said last named cylinder and a part capable of independent rotation thereto, one of said parts being movable longitudinally of the axis of said cylinder and means for causing an angular displacement of said independently rotatable part with respect to said cylinder upon the relative movement of said parts longitudinally of the axis of said cylinder.

2. In a rotary printing machine, two cylinders operatively associated with each other, and adapted to carry printing surfaces, gear wheels one for each cylinder in mesh with each other, one of said gear wheels being capable of independent rotary movement relative to its corresponding cylinder, means for connecting said gear wheel to its corresponding cylinder comprising a part mounted for rotation with said cylinder and a sliding connection between said part and said gear wheel capable of changing the angular position of said gear wheel with respect to its cylinder upon relative movement longitudinally of theaxis of said cylinder. Y
